The “Deck Belt” goes around the pulleys right above the blades on the deck and then to a double pulley. The “Drive Belt” on your mower goes from the transmission, around an Idler pulley then over to the double pulley I mentioned before. The Drive belt also plays a role in making the wheels turn.
Since you`ll likely only replace your serpentine belt once during the life of your car, it`s generally recommended to take your car to a professional mechanic. You can do a lot of damage to your vehicle if you drive on the road with an improperly installed serpentine belt.
Yes, with a few tools. Use a long-handled socket wrench to loosen the tensioner. This will allow you to remove the old belt. Wind the new belt correctly through each of the parts that run on the serpentine belt.
To replace the output belt also known as a toothed belt or timed belt, we need to remove the deck from the mower. It`s not difficult to do, and the whole job shouldn`t take more than an hour.
Deck Drive Belts and Transmission Drive Belts for self-propelled models.
The top belt is the power clutch belt, also known as the PTO (power takeoff) belt. This is the easier one to replace because it`s on top and has a spring-loaded hand lever to remove the belt from the lawn mower for deck removal. The lower belt on the deck is called the arbor belt.

May I get the make and model # to get you the right belt diagram
The belt that comes from the engine to mower deck keeps breaking. I’ve owned the mower for years and I have to buy atleast 12 belts per year. The problen is really bad now. A belt per cutting. I’ve raised the deck, tightened and loosened the tention, sharpened blades, changed to B v-bets to A, nothing seems to work. Changing the sise to a smaller width helped for a while. I had a service man come out my first month. He said the mower is fine. Claimed cutting to deep has to be the problem and left. I used a Ford 12 hp mower since high school 25 years ago……….no problems with it. Thought I should buy a new one because the old one looked rusty…. big mistake buying Craftsman.
I own a Craftsman rider, DTY 4000, 25 HP Kohler, 48″ cut, 137 Hrs. It eats a belt about every mowing or two. Did all the stuff you did. Good luck from Sears. Had cousin who is owns a lawn & garden repair business look at it today. Says the prob. is this – The drive belt pulley (elec clutch) has too a narrow “V” and the angle of wear between it and the deck when the deck is in the lowered (mowing) position is too severe. If you notice with the deck in the fully raised position the pulleys line up perfectly. Then drop your deck and see how tightly bent the belt is downward and it makes sense as to why(my) belt would first roll over then break in a few minutes. The elec clutch pulley is sold as one unit PT No. 179334 $250.00, but I’m sure it would come with the same narrow V pulley. Waiting for word from my cousin. My last Sears Mower. Cannot even sell it in good faith.
I need to change the deck belt, but i don’t know what to loosen to accomplish this
Loosen the belt tension lever on the left side of the deck …. then remove the right side blade pulley black plastic cover to remove the old belt….. the new belt goes on easily…. 15 min. job
LT1045 keeps breaking NEW belts after just a short period of mowing.

Got a craftsman mower 42 inch deck changed spindles and blades and deck still shakes belt may not be tightening up
Did you put the blades on right ??? they have a star pattern and it needs to be lined up correctly… if that’s ok does the belt have a bad spot in it or is the engagement mechanism operating correctly ???
